Internal-combustion-engine fuel



MIL'I ON C. WHITAKER, OF YORK. N. Y., ASSIGNOR TO U. 'S. INDUSTRIALALCOHOL CO., A CORPORATION OF WEST VIRGINIA.

INTERNAIJECOMBUS'IION-ENGINE FUEL.

T 0 all whomit may concern.- A Be it known that I, MILTON C. YHITAKER, acitizen of the Fnited States, residing at New York, in the county of NewYork and State of New York, have invented a certain new and usefulImprovement in Internal- Combustion-Engine Fuel, of which the followingis a specification. f

My invention relates particularly to fuels designed to be'used inaeroplane motors, but is applicable for use in internal combustionmotors of all kinds used in flying or for other purposes. 2

The object of my invention is to provide a fuel which is especiallyadapted for use n aeroplanes, although it is also applicable for.

use in internal combustion engines in general.

n It is necessary that fuels which are to be used in aeroplane motorsshall have great dependability, inasmuch as any uncertainty in theoperation of the aeroplane by reason of variability in the character ofthe fuel or failure of the fuel to perform 'its intended work, may bringabout disastrous consequences.

For this reason, it is desirable to avoid -...,,using in such fuelslarge percentages of petroleum products, inasmuch as commercialpetroleum products do not ordinarily have a constant composltlon', andare-usually comprised of varyingquantities of a number of differentconstituents. It is, therefore, the object of my invention to provide amotor fuel avoiding these dis advantages and taking into account thecircumstances above referred to.

Still a further object of my invention is to provide fuels of'the abovecharacter by the use of ketones but especially higher ketones, that isto say, ketones other than acetone.

Further objects of my invention will appear from the detaileddescription thereof contained hereinafter.

While my invention is capable of being carried out in different ways, rthe'purpose ofrillustration I shall describe only certain ways ofcarrying out the same herein.

For example, a fuel made in accordance with my invention may becomprised of 35-parts by volume of acetone,

25 parts by volume of. alcohol,

5 parts by Volume of ethyl acetate,

Specificationcf Letters Patent. Patented June 2Q, 1922 Application filedNovember 12, 1919. Serial No. 337,395.

17% parts by volume of. kerosene,

17% parts by volume of gasoline.

Another example is:

35 parts by volume of methyl-ethylketone, V

25 part'sby volumeof alcohol,

5 parts by volume of ethyl acetate, 17% parts by volume of kerosene, &

17 1}; parts by'volume of gasoline.

Another example is:

35 parts by volume of diethylketone,

25 parts by volume of alcohol,

5 parts by volume of ethyl acetate, 17% parts by volume of kerosene,

17:1- parts by volume of gasoline.

The above compositions may be varied to a considerable extent. Forexample, the kerosene and gasoline may be substituted by the same totalquantity of a single petroleum distillate, such for example as gasolineor kerosene. Instead of ethyl acetate, I may use any oneof a number ofesters, as for example methyl butyrate, ethyl butyrate,

2. A fuel comprising approximately equal proportions of a ketone, analcohol, and a light petroleum distillate, with a smaller I proportionof a volatile ester.

3. A fuel comprising a light hydrocarbon, alcohol, diethyl ketone andethyl acetate.

4. A fuel comprising about 35% ketone,

about 25% alcohol, about 35% pe troleum distillate, and about 5% of anester."

5. I i fuel comprising about 35% diethyl ketone, about 25% alcohol,about 35% petroleum distillate, and about 5% ethyl acetate.

In testimony that I claim the foregoing, I have hereunto. setmy handthis 6th day of November, 1919. i
